"Hen-Coop Rag" is a characteristic example of early ragtime music, a genre known for its syncopated "ragged" rhythm that became a craze in the United States at the turn of the 20th century. While not one of the most famous rags by composers like Scott Joplin or Joseph Lamb, titles like these were common, often depicting scenes of everyday life, animals, or humorous situations in a light-hearted, playful manner. The music likely features a lively, marching tempo and a melody that mimics the clucking and bustle of chickens in a coop.
